Each talk is about 50/60 minutes long, DV compression is about 10Gb/hour. Means that I have to process 60Gb of stuff.
I have everything on tape, luckily enough, because I have only 20Gb of disk left ("only 20gb of disk", can you believe that I thought that? god)
I'm encoding using iMovie, pretty cool, very simple to use and very efficient. Final Cut Pro or AVID Digital Studio are another planet, but hey, cutting and post-production here is *really* simple ;-)
I'm encoding with DivX 5.1 beta, shaky and slow as hell, but it seems to be portable across all systems.
It needs 8 hours per hour on my G4 1Ghz (at max processing quality). This means that it would take me 1.5 CPU days!!!! to encode the GT, plus another few days to upload it. hope my CPU doesn't melt down.
I encoded at video at single pass, constant rate, 320x240, 100kbps and audio at mp3 16bit 22Khz 64kbps mono.
Video artifacts are terrible when there is some motion (divx is really poor at small bitrate) but audio is pretty good.
Interesting enough, encoding video at 200Kbp didn't change the picture much (artifacts were reduced, but still not good enough to see anything, so I left them like that).
Expected size per presentation is around 50Mb/60Mb, which isn't bad at all.
In case you have suggestions, yell now because each mistake is 8 hours of processing :-(
I'll make the first talk available tomorrow, after merlino (my laptop) finishes crunching it to night.
and then I'll wait for comment before moving on.
time to go to bed now.
